MPROVEMENT IN BX-FASTENERS.

Specification forming part of Letters Patet No. 219.708, dated September 16, 1879; application filed March 15, 1879.

' declare the following to be a full, clear, and

exact description of the same, reference being made to the accompanyn g drawings, forming a part of this specification, and inwhich Figure 1 represents a longitudinal vertical section of a slipping case or box, showing my improvements as applied thereto; Fig. 2, a

,bottom-plan view of the cover to which the fastenings are secured.

My invention relates to certain new and useful improvements in fastenings for seour ing the covers on shippin g cases or boxes, and more particularly to the class employin g concealed spring-catches or fasteni'gs operated through a slot or opening extending entirely through the end or side of the shipping case or box; and theinvention consistsin the combination, with ashipping case or box havingaslot or opening throughthe end or side thereot', of a cover provided on its under side with a spring catch or bolt having its nose beveled outward and upward, and which engages with said slot or opening in the case or box, whereby inserting the blunt end of a pencil, stick, or other suitable instrument through the slot or opening from the outside and pressing against the beveled' nose of the spring catch or bolt it will be raised, so that When free from its keeper the force of the spring and the beveled nose of the catch will partially raise the cover, thus facilitating its removal..

In the drawings, A represents a shipping case or box having an interior slot or opening, F, in one end to receive the strip D, secured to one end of the cover B, and which forms the coverfastening at that end of the case or box. The other end of the case or box is provided With a slot or opening, E, passing entirely through it, and with which a spring catch or bolt, O, secured to the under side of the other end of the cover, is adapted to cngage when the cover is forced down tight onto or in the case or box.

The spring catch or bolt has its engagingnose beveled outward and upward, -so that in passing a blunt instrument from the outside into the slot or opening for pressing back the spring catch or bolt to unlock the cover, said catch will be raised, so that the force of the spring and the beveled nose, when free from the keeper, will partially raise the cover, thus greatly facilitatin g its renovalwithout the aid of other auxiliary devices.

In shippiug, the address label or card may be Secured over the slot or opening in the end of the case or box, concealing said slot or opening, thus preventing the case or box be- 'ing opened during transit without destroying the label or card.

I am aware that spring catches or bolts provided with similar beveled noses, and also packin g cases or boxes provided with interior concealed spring-catches or other fastenings for securin g the cover thereon, and which are unlo'cked by passing a suitable instrument through a slot or opening in the side or end of' the box, are old, and such I do not desire to claim, broadly, as my invention, but,

Having thus fully described my invention, what I do claim as new, and desire to secure by Letters Patent, is

The combination, with a shipping case or box having a slot or opening, E, through one end or side thereof, of the cover provided with a spring catch or bolt having an outward and upward beveled nose for engaging With said slot or opening, whereby in'pressin g back the catch` or bolt to unlock the cover said catch will be partially raised, and then the force of the spring and the beveled nose ot' the catch, when free from the keeper, will partially raise the cover, substantially as shown and described.
